I received an electronic signature email, but it didn't pass.

If you receive the verification code inexplicably, you should pay attention to it. General login software, registration information will use verification code. If you don't do the above, it means that someone else has entered your mobile phone number wrong, or wants to log in or register with your mobile phone number or something. At this time, don't leak the verification code to others, so as not to be deceived or cause economic losses.
